What is your favourite colour? Do you like yellow , orange ,red? If you do ,you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer greys and blues? Then you are probably quiet,shy, and you would rather follow than lead. You tend to be a pessimist. At least, this is what psychologists tell us, and they should know,because they have been seriously studying the meaning of colours preference, as well as the effect that colours have on human beings. They tells us, among other facts,that we do not choose our favourite clour as we grow up----we are born with our preference.If you happen to love brown, you did so, as soon as you opened your eyes, or at least as soon as you could see clearly.
Colours do influence our moods----there is no doubt about it .A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand ,black is depressing. A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area ----until it was repainter green.The number of suicide attempts immediately fell sharply ;perhaps it would have fallen even more if the bridge had been done in pink or baby blue.
Light and bright colours make people not only hppier but more active. It is an established fact that factory workers work better,harder ,and have fewer accidents when their machines are painted orange rather than black or grey.
If one enjoys life, one is sure to prefer________.
a.red to yellow
b.blue to orange
c.red to grey
d.blue to yellow

The traffic lights were red when the driver reached them．To the surprise of his passenger,the ear did not slow down．Unexpectedly the passenger was thrown forward in the vehicle as the driver put on his brakes at the last moment．The car stopped just in time.
"Sorry,I didn't notice the light．I thought it was green until I saw that it was the top light which was shining."
This strange story is quite true．About ten men in every hundred are color blind in some way;women are luckier--only about one in two hundred suffers from color blindness.
In some cases,a man may not be able to see deep red．He may think that red,orange and yellow are all the same as green.
People often like one color more than others．Blue is the color of the sky and sea．Green makes us think of fields and trees．Red is the color of blood and makes some people think of danger．Black is the color of night．In the dark we cannot see what is around us so we are sometimes afraid of the unknown and do not like black as a color.
One is considered as a color blind man if__.A.he can see the difference between red and deep red
B.he can see the difference between blue and green
C.he can't tell the difference between orange and green
D.he thinks green is the same as blue

第三篇Ways to Create Colors in a PhotographThere are two ways to create colors in a photograph.One method called additive,starts with three basic colors and adds them together to produce some other color. The second method,called subtractive,starts with white light(a mixture of all colors in the spectrum)and,by taking away some or all other colors,leaves the one desired.In the additive method,separate colored lights combine to produce various other colors.The three additive primary colors are green,red and blue(each providing about one-third of the wavelengths in the total spectrum).Mixed in varying proportions,they can produce all colors.Green and red light mix to produce yellow,red and blue light mix to produce magenta(a purplish pink);green and blue mix to produce cyan(a bluish green).When equal parts of all three of these primary-colored beams of light overlap（重叠）,the mixture appears white to the eye.In the subtractive process colors are produced when dye（染料）absorbs some wavelengths and so passes on only part of the spectrum.The subtractive primaries are cyan,magenta and yellow; these primaries or dyes absorb red,green and blue wavelengths respectively,thus subtracting them from white light. These dye colors are the complementary colors to the three additive primaries of red,green and blue.Properly combined,the subtractive primaries can absorb all colors of light, producing black.But,mixed in varying proportions,they too can produce any color in the spectrum.Whether a particular color is obtained by adding colored lights together or by subtracting some light from the total spectrum,the result looks the same to the eye.The additive process was employed for early color photography. But the subtractive method,while requiring complex chemical techniques,has turned out to be more practical and is the basis of all modern color films.Which of the following is NOT a pair of additive and subtractive primary colors?A:Yellow and blue. B: Magenta and green.C:Black and white. D:Cyan and red.
